To allwhom it may concern:

Be 1t known that I, ROBERTG. BuLLAnn,

a citizen of the United States, residing at T he invention has for one of its objects to provide a cross-tie of simple, substantial and durahle construction, and Whiehis co1nparatively easy and inexpensive to manufacture.

A further object of the invention is to provide a simple and effective fastening device for attaching the rails to the cross-ties and for preventing the rails from spreading, the parts being so designed that the rails can be quickly and accurately laid and taken up with facility, in reconstructing the railroad track. I

Another object of the invention is to provide a tie composed of two sections whereby the tie can be readily handled, each section being provided with oppositely extending arms disposed at such a point as to lie under the rails so as to afford supports therefor and thereby permit the ties to be laid at a greater distance apart than usual and. at the same time producing a strong and substantial foundation for the rails.

With these objects in view'and others, as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more fully described hercinaftorand set forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustratcs one of the embodiments of the inven tion, Figure l is a perspective View of a portion of a railroad'track eonstructeddn accordance with the invention. Fig. 21s a longitudinal section of one of the cross-ties. Fig. 3 is a plan View of a cross-tie with the rails fastened thereto. Fig. 4 is a section on line 4-.;-4, Fig. 2. Fig. 5 is a perspective view of one of the fastening bolts.

Similar reference characters are employed to'dcsignatc corresponding parts throughout the several views.

Referring to the drawings, A designates the track rails "which are of standard construction and laid upon ties B. These tics, in the present instance, are molded of con- 'tWO sections 1 and 2.

i been laid.

creteor other suitable material and made in The sections are of any suitable size' and are preferably reinforced by barsfi of iron, said bars being spaced apart as shown clearly in Fig. 4 for t e purpose hereinafter to appear.

Extending vertically through each section is a bolt-receivingpassage 4 disposed at the inner edge of the base ofthe rail, .as shown in Fig. 2, and the reinforcing bars are spaced apart at o )posite sides of this assage for pen mitting the bolt 5 to pass between them. The head of the bolt, as shown in Fig. 5, is rectangular so that the bolt can be placed in. the tie or removed therefrom after the tie has The belt is inserted in the passage 4 with the head 6 thereof lowermost and after it is fully inserted, the bolt is given a quarter turn so as to engage the ends of the head under the metal lparts or reinforcing bars 3, the shanlr of the'bolt being oi sufficient length to project from the top of the tie. The tie sections are preferably formed with oppositelydlisposed arms 7 at points directly under the rails A whereby the rails will be supported. at all points. Tlhcse cruciform tiesections are laid with the inner ends 8 together, and the top surface of each sec-- tion has a depression 9 directly under the rails for receiving the extremities of the tie bars 10. These tie bars are so designed. as to prevent the rails from spreading and also to cooperate with the ballast of the roadbcd to prevent the tie sections from spreading. The bar 10 is offset at 11 for engaging the shoulders 12 or inner walls of the recesses S), thereby ell'cctively holding the tie sections in place. and the offsets provide shoulders 13 for receiving the fastening plates 14 that engage the bases of the rail sections at the inner sides thereof. The-plates 14 are aerturcd to receive the bolts '5 as also tie ollsct extremities 16 of the tie bar 10. The ends of the oll'sct e ztrcinitios are formed into baseengaging hooks 17 that hook over the bases of the rails at the outsides thereof. These hooks co-act with the plates 14 to firmly hold the rails in. position, and as the bar 10 is made in one piece, it serves the tln'ce-fold function of holding the tie sections 1 and 2 in contact with each other, to prevent the rail sections from spreading and to secure the rail sections to the ties.

The inner or meeting ends of the two sections are inclined oppositely fl'OIlflll'M-t ton to over the track.

l roin the foregoing description, taken in connection with the accompanying drevving;

the advantages of the construction and oi the method of operation will be readily apparent to those skil ed in the art to which the JHVOD- tion appertnins, and while I have described the principle of operation of the invention, together with the (lGVlCG which I new conside," to be the best embodiment thereof, 1

desire to have it understood that the device z-i iiowii'i. is merely illustrative and that sneh p may he made when desired as are the reope'of the claims.

mg thus deserihed the invention, whet eross tie eoniprising erueii'orin seetions mode oi eonerete each having it vertienl "go and n depression in the top sin-hire which the :ii'id outer walls ol said pessno e opens, the inner the sind depression lorinii shoulders, and ii reinforcing device enihedded in each seetn'in and provided with spaced members ioeeted et opposite sides of the nessnge, in ooinbinntion with it tie her exten ing from one section to the other ol' the tie ene'provided with depres l ends seei ed in the eepression )l' said sections ol' the tie, and. the extre es of the ends being bent upwardly and inwardly to form rail-engaging I hooks, rails extending over the depressed l ends of the tie her and. having their bases enl geged under the hooks, clamping plates erl ranged at the insides of the rails and engagl ing the bases thereof, shoulders on the tie ber l with whieb the inner ends of the 7 l plntes engage, holts in the passages of the said seetions and passing through apertures in the tie her and clumping plates, eneh belt having an elongated head shaped to p'lss hetween the members of the reinforcing device in ositioning the bolt and also provided with e non-circular portion adjacent the hood for engaging: between the said men'ihers ol' the reinforeing device to prevent turning of the bolt, and n nut on the upper end of each bolt for elzinwing the parts together.
